[TowerTalk] 4 square arrays - taper example

[mpride@us.ibm.com]

My 80 M 4 Sq. is made from 40 ft. of Rohn 25, topped off with some aluminum
tubing that is approximately 30 ft. in length.  The drop in diameter from
12 inches (Rohn 25) to 2 to 1.5 inches means one needs to extend the length
to properly resonate the element.  This sits on 20 ft. of Rohn 25 with 8
elevated radials.   Overall element length is around 70 ft., the overall
height of the tower/tubing is 90 ft.  Works just fine!

Regards,

Mark, K1RX
